FLUSHIN G DEVICE.

VSpecification of Letters Patent.

Patented J une 5, 1917.

Application led August 21, 1913. Serial No. 785,938.

To all ywhom t may concern Be it known that I, Janne F. DE SPIRITO, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Flushing Devices, of which the following is a specification.

This invention relates to flushing devices particularly adapted for use in connection with water-closets, having for one of its objects to construct a device which will allow for the flow of water during a greater or less definite period of time.

Another object which this invention contemplates is the provision of a device of this character in which the initial ow of Water opens the valve for allowing the water a direct flow into the bowl of the closet and at the same time automatically closing the valve, after a predetermined quantity of water has been flushed.

Other objects as well as the nature, characteristic features and scope of my invention will be more -readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification.

Referring to the drawings Figure l is a vertical sectional view of the device constructed in accordance with my invention; and

F ig. 2 is a cross sectional view taken on the line 2--2 of Fig. 1. t

In the drawings wherein is illustrated the preferred embodiment of this invention a casing 5 is provided which in the present instance is preferably of a cylindrical configuration, having formed in one of its sides a transverse inlet opening 6 which connects with a way 7, the latter being formed in the side of the casing and extending longitudinally therethrough, the mouth of the way 7 being extended downwardly as indicated at 8 so as to facilitate the entrance of the water from the inlet 6 thereinto. Arranged at a diametrically opposite point on the casing 5, from the way 7, is a way 9 which has connection at one end with an outlet 10, the latter emptyingA into the bowl, while'the opposite end of said way is in communication with the way 7 which is usually closed through the medium of a construction which will be presently described.

The upper end of the casing 5 is provided with internal screw threads 11 which are engaged in threaded relation with the externalthreads of the bonnet or cap 12 which is arranged thereon, the cap 12 being provided with an annular depending flange 13 which extends in parallel relation to the body portion of the bonnet for a short distance, and has mounted between the inner periphery thereof and the outer periphery of the body portion an elastic washer ll, to prevent the leakage of water from the interior of the casing 5 through the threads 11 and the threads of the bonnet 12 to the exterior of the casing, as is sometimes the case. The bonnet l2 has formed on the inner end thereof an annular collar 15 which has formed therein registering apertures 16 which aline with an aperture or opening 17 in a cap or plate 18, said opening 17 having connection with the way S) of the casing 5. The cap 18 has depending therefrom a collar 19, the outer face of which extends inwardly in spaced relation from the marginal edge of the cap, the inner fache of said collar having screw threads formed thereon which engage with the screw threads of the valve chamber 20, the latter being so constructed as to provide a seat 2l for the coil spring 22. Mounted for vertical movement in the valve chamber 20, is a valve 23 which comprises a disk having an `annular flange 24 provided on the upper face thereof and a concentric socket 25 which has rigid engagement with the free end of the handle stem 26. The opposite face of the valve disk has depending therefrom a stem 27 directly below the socket 25, said stem being engaged by the convolutions of the coil spring 22. Formed at diametrically opposite points in the valve chamber 2O are openings 28 which connect with the interior of the casing 5, and permit the entrance of fluid through the way 7 and into the way 9, when the valve 23 is disengaged from its seat.

The bonnet or cap l2 has formed therein a central opening in which is mounted a stuiling box 29 the latter being detachably arranged therein and having depending therefrom anelongated annular flange 30,

fory allowing connection ybetween the waysfi7 and 9 as previouslypointed out. To unseat the valveQ-S, the'handle 32 is firstrotated, and slight pressure'k then exerted thereon, which operation Causes the complemental f distorted faces of washers vto slide over eachother; the lower of the washers which is vshown in Side elevation in F ig. 1 is fiXedly n secured to a shank depended from the handle 32, while the other washer, which is shown in section in Fig. 1, is fixedly engaged with the upper end of the casing 5, thereby permitting said shank to be forced downwardly for unseating the valve 23, and permitting said handle to be automatically raised to its normal position by the spring 22, as soonas pressure is released from the handle.

The casing 5 has threaded in the slde thereof a needle valve 33 which has engagement through the way 7 for controlling the flow of water therethrough and into the interior of they casing, through an opening-34 which is formed therein, the needle valve 33 being enlarged eXteriorly of theway 7 and provided with external screw threads which are in engagement with the internal threadsiof a cap 35. rl`he end of the valve, beneath the external threads thereof, is squared as indicated at 36 for, facilitating the actuating of the same.

"Mounted for movement on the interior of the 'casing 5 and normall l ino* on a valve seat 3T which is formed 1n said casing adjacent the outlet 10 thereof is a valve 33 which is preferably of a substantially cylindrical configuration conforming to the interior of said casing, having a portion 39 thereof cut out, and the upper end thereof provided with screw threads forengagement with the washer retaining element 40, the latter comprising a disk having depending therefrom n y an externally screw threaded collar, said eX- ternal threads lbeing arranged in spaced' relation from ythe peripheral edge of they disk. Extending'over the top of the valve 38 and having engagement with the side thereof fork a portion of its length, is a flexible washer 41 which may be of any suitable material, and, is held in engagement therewith through the medium of the element 40 heretofore described. The opposite or lower end y of the valve 38 has formed therein a thread rbination with a. casing Leashes the casing 5, thus causing the" valve 38 tobey normally engaged on the seat 37. When it is desired to flush the water through the openc ing k10, the handle 32 is eithery turned o1." forced. inwardly, which operation will unseat ythe valve 23, in view of the peculiar formation ofy plug which is advantageously illustrated iny Fig.y 1 causing said valver 'to operate in a vertical plane in a manner here tofore set forth. When the valve 23 is removed from its seat 44:, thelatter being formed on the' end of the flangeV 30, and engages with the annular flange 24of saidk valve, it will be seen that the watergis al lowed to flow through the openings 28 in the valve chamber QO'and upwardly through the apertures 31 of the elongated flange 30,

kand outwardly through the apertures 16 and 17 into the way 9, thence into the outlet 10. beneath the valve k38. By unse'atingthe valve 23, it is seen that'there is a diminution of pressure on the member 40 causedk by the flowing of the water through the Wav 9, thereby permitting the valvek 38 to be over? balanced by the pressure of the water in the inlet The valve 38 is therefore unseated,l permitting a direct flow of water through the inlet 6 and into the outlet 10y to the bowl of the closet.y Only a limited amount of wa-' ter will be allowed to low directly throughy the inlet 6 and into the outlet 10, in view of the fact that after the Vvalve 23 has been unseated, a constant pressure is exerted on the lower face thereof by the ycoil springL 2Q, ywhich is undery tension when said valve is unseated. It will be readily obvious that as soon as the flange 24 of the valve 23 is in engagement with the valve seat 44, communlcation 'will be cutofbetween the ways 7 and 9, thereby preventing the flow bf Water therethrough, and causing the chamber above the member 40 to be replenished for reseating the valve 33, f

I't will be understood that the above description and accompanying drawings comprehend only thevgeneral and preferred em bodnnent of my invention and that various minor changes in detail of construction, proportion aud arrangement of the parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.
